Le procédé comprend l'étape consistant à mettre en contact la surface avec une composition de nettoyage comprenant (a) de 5 à 50 % en poids d'un tensioactif anionique, (b) de 5 à 50 % en poids d'un premier tensioactif non ionique répondant à la formule générale R'-(AO)n-OH, dans laquelle R' représente un groupe alkyle en C9 à C20, chaque motif AO représente soit -OCH2CH2- soit -OCH2CH(CH3)- et n est supérieur à 6, et (c) de 5 à 50 % en poids d'un second tensioactif non ionique répondant à la formule générale R'-(OCH2CH2)n-OH, dans laquelle R' représente un groupe alkyle en C9 à C20 et n est inférieur à 6; chacun desdits pourcentages en poids étant par rapport au poids total de (a), (b) et (c). Le procédé est en particulier utile pour le nettoyage de surfaces internes profilées de citernes à marchandises pour le transport maritime. L'invention porte également sur les compositions de nettoyage pour surfaces dures correspondantes à la fois sous forme concentrée et sous forme diluée avec de l'eau.
